Long-Term Bowel and Urinary Function Outcomes and Quality of Life in Patients with Anorectal Malformations: 20 Years of Experience.

Background: Anorectal malformations (ARMs) are rare congenital anomalies requiring surgical correction and long-term multidisciplinary care. Despite advances in surgical techniques like posterior sagittal anorectoplasty (PSARP), patients often experience ongoing issues with bowel and urinary function and psychosocial well-being. Aim: To evaluate the long-term outcomes of bowel function, urinary function, and quality of life in patients born with anorectal malformation and treated at our center. Methods: A cross-sectional study evaluated 55 ARM patients treated at the University Hospital of Palermo between 2002 and 2020. Data on clinical characteristics, surgical management, bowel and urinary function, and quality of life were collected using the following validated tools: Rintala Bowel Function Score, PedsQL Family Impact Module, Fecal Incontinence Quality of Life Score, and Lower Urinary Tract Symptoms Questionnaire. Statistical analysis was performed using Fisher's exact test and ANOVA. Results: Excellent bowel function was observed in 44% of patients, particularly those with low-type ARMs. A bowel management program (BMP) was required in 62% of cases, though 44% of these patients, especially adolescents, showed poor adherence. BMP non-adherence significantly correlated with lower quality of life and worse bowel function (p < 0.01). Bladder dysfunction was noted in 24% of patients, mainly younger ones. Conclusions: Tailored BMPs and transition care are important for long-term success in ARM patients. Adherence to BMPs improves continence and quality of life, highlighting the need for continuous, multidisciplinary follow-up from childhood into adulthood.
